Rain Detection System
A Rain Detection System using Arduino, a rain sensor, and a buzzer that sounds an alert when water droplets or rain are detected.
Description
The Rain Detection System is designed to detect rain using an Arduino and a rain sensor. When the rain sensor detects water droplets, it sends a signal to the Arduino. The Arduino processes this signal and activates the buzzer to produce a sound alert, indicating that rain has been detected. This project is useful for weather monitoring, automated window control, and irrigation systems.

A Battery High-Low Monitor is an electronic circuit or device that detects and indicates the voltage level of a battery — whether it’s too high (overcharged), normal, or too low (discharged). It helps protect batteries from overcharging or deep discharge, which can damage the battery or reduce its lifespan.
These monitors often use comparators, voltage dividers, LED indicators, or microcontrollers to track and display battery status in real time.

A Bird Bell is a device designed to either attract, entertain, or repel birds, depending on its purpose and context. Traditionally, it is a small bell-shaped object made of metal, ceramic, or wood, and is usually hung in gardens, balconies, farms, or near bird feeders. Its name comes from its interaction with birds — it may ring when birds land on it, brush past it, or when the wind causes it to move.

An AND gate can be built using BC547 NPN transistors, a common general-purpose transistor used in digital circuits.
The circuit represents both the inputs A & B for the AND gate and Output, Q, which also has a +5V supply to the collector of the first transistor, which is connected in series to the second transistor, and an LED is connected to the emitter terminal of the second transistor. The inputs A & B are connected to the base terminal of Transistor 1 and Transistor 2, respectively, and the output Q goes to the positive terminal LED.
